#### [Docs](https://smwb-tech.gitbook.io/vue-flash-message/)
## Setup
```
npm i @smartweb/vue-flash-message
```
## Installation and Configuration
Register the component in your app entry point (main.js or as you called it)
```javascript
import Vue from 'vue';
import FlashMessage from '@smartweb/vue-flash-message';
Vue.use(FlashMessage);
```
You can pass [configuration object](#configuration-object) as second argument
```javascript
Vue.use(FlashMessage, config);
```
### Nuxt.js
Create vue-flash-message.js file in plugins directory and put the following code:
```javascript
import Vue from 'vue';
import VueFlashMessage from '@smartweb/vue-flash-message';
Vue.use(VueFlashMessage);
```
In your nuxt.config.js file register your plugin
```javascript
{
/* Since Nuxt.js 2.4, mode has been introduced as option of plugins to specify plugin type, possible value are: client or server. ssr: false will be adapted to mode: 'client' and deprecated in next major release.
More info: https://nuxtjs.org/guide/plugins#client-side-only */
plugins: [{ src: '~/plugins/flash-message.js', mode: 'client' }]
},
```
### Configuration object
---
| Property | Type | Description | Default |
| ------------ | ---------- | ------------------------------------------------------------------------------------------------- | -------------- |
| **name** | **String** | It is a name of the component and alias for the EventBus global property. | 'flashMessage' |
| **tag** | **String** | Custom tag for the component to use in your application. | 'FlashMesage' |
| **time** | **Number** | Duration (in ms) of the message display (can be customized during message call). | 8000 |
| **strategy** | **String** | You can pass 'single' or 'multiple' to choose the default strategy. It can be changed in process. | 'single' |
## Usage
Put the component into your template
```html
```
You can pass a string as position property to set up default position of messages block. Valid values: **'right bottom'**, **'right top'**, **'left bottom'**, **'left top'**.
```html
```
Now you can access flash message by using global EventBus alias (that is "flashMessage" by default) of your Vue instance
```javascript
this.flashMessage.show({
status: 'error',
title: 'Error Message Title',
message: 'Oh, you broke my heart! Shame on you!'
});
```
## Methods
### Display Methods

Every display message method will return the id of the message instance
```javascript
this.flashMessage.show({
status: 'error',
title: 'Error Message Title',
message: 'Oh, you broke my heart! Shame on you!'
});
```
You also can use shorthands without status property.
```javascript
this.flashMessage.error({
title: 'Error Message Title',
message: 'Oh, you broke my heart! Shame on you!'
});
this.flashMessage.warning({
title: 'Warning Message Title',
message: "Don't stop me nooooow....!"
});
this.flashMessage.info({
title: 'Info Message Title',
message: 'Just want you to know, that Vue is so cool'
});
this.flashMessage.success({
